The management of critical equipment aboard ambulances involves not only ensuring that each item intended to treat a patient is onboard when needed, but also providing scheduled maintenance and servicing to guarantee that if a piece of equipment is required during an emergency, it will function as expected. East Midlands Ambulance Service (EMAS) NHS Trust is tracking onboard equipment within its ambulances via an RFID solution known as CheckedOK Medical. The solution, provided by CoreRFID, consists of EPC Gen 2 ultrahigh-frequency (UHF) passive RFID tags applied to medical equipment (such as resuscitators, ventilators and monitoring devices), as well as handheld readers to capture the ID numbers encoded to those tags, and software residing on CoreRFID's hosted server that stores data indicating which items are in which vehicle and when they were serviced.

EMAS, which operates its emergency vehicles in Derbyshire, Leicestershire, Rutland and Lincolnshire counties, employs 2,700 staff members and operates 450 vehicles. Each vehicle should be stocked with a specific set of tools and equipment for use in treating patients until they can be transported to a hospital. Prior to deploying the CheckedOK system to manage the thousands of assets that need to be stocked on those vehicles, EMAS maintained a file on its database listing each item. Personnel could search the database to identify which pieces of equipment should be on which vehicle, and learn about their history, as long as that data had been properly entered and updated, says Richard Needham, East Midlands Ambulance's assistant head of fleet. Without the use of RFID, however, the company could not always ensure that every ambulance had the equipment it needed, even if the software indicated those items were onboard.

The company began working with CoreRFID last year to create a solution, says Adam Robinson, CoreRFID's sales manager. CoreRFID had originally developed CheckedOK in 2011 for the construction, engineering and facilities management industries, and modified the system for EMAS, launching CheckedOK Medical in April 2013. CheckedOK Medical includes two types of passive EPC Gen 2 UHF tags, to accommodate the equipment's different materials and form factors, as well as handheld readers. CoreRFID's software manages the collected read data on its own hosted server.

According to Needham, East Midlands applied Confidex's Carrier Micro and Xerafy's Titanium Metal Skin RFID labels to such equipment as resuscitators, defibrillators and suction units, for a total of approximately 3,000 to 4,000 items.

Every month, all equipment is removed from each ambulance and cleaned, then is checked against the inventory listed in the database and returned to the same vehicle. If maintenance is due for a particular asset, that item could be replaced, or it could be serviced before being returned to the ambulance. Multiple vehicles are often emptied side by side, which could result in equipment being moved into the wrong ambulance.
